Dark Tube heater type AK-HL can be used in many different places. Our tube heaters consist of a burner unit with a built-in "press" fan with a venturi burner. This has the advantage over tube heaters with a fan at the end of the radiation tube that the fan is not exposed to high temperatures.

This benefits the life of the fan and the efficiency of the device. This allows us to create a very long laminar flame that extends far into the radiation tube with an even heat transfer to the radiation tube. The radiation tube is heated to 650 ° C and therefore generates pleasant heat radiation. Another advantage is that the devices are modular in structure and are provided as standard with a power control with which the power output can be regulated between "full" and "half" load.

Benefits of tube heaters:
• Extremely high efficiency more than 90%
